The pressure is all on West Ham

After avoiding potential early round banana-skins with the away wins over Newport County and Oxford United, it is Rovers' turn to hopefully provide the cup shock when the Hammers come to Ewood Park in Sunday's 2.00pm clash.

Lambert admits nobody outside of Lancashire expects Rovers to defeat Slaven Bilic's impressive outfit, but with the visitors being the favourites all the pressure is on the Premier League side.

"It is a great game for us because other than ourselves and our fans nobody expects us to win," said the Scot.

"The pressure is all on West Ham, that is normal because they are a Premier League side coming to a Championship side.

"But I expect us to win, I go into every game thinking that, that is what we have always done."

Despite being the underdogs Rovers have shown in recent years that they can rise to the big occasion.

Last season saw Swansea City and Stoke City both defeated at Ewood Park, before Liverpool were taken to a quarter-final replay.

So the manager believes there is enough big match experience in the squad ready for tomorrow's clash.

"We've one or two that play for their international teams so they know what the big occasion is like, they've played in front of large crowds before," he added.

"So the game won't phase them, they won't be like a rabbit in the headlights, they'll be ready for it.

"We also know that we need to play well to get through and we maybe need West Ham to be off their game a little bit. But for 90 minutes it can happen.

"We've got everything to gain and nothing to lose because nobody expects us to go through, other than ourselves.

"So there is no pressure on us, for West Ham the pressure is there."

Fans who haven't yet purchased their tickets for Sunday's match are advised to get them well in advance of the 2.00pm kick-off as large queues at the ticket office are anticipated.
